About

Senior Software Engineer & Tech Lead with over 9 years of experience, I specialize in designing and implementing scalable, performant, and maintainable web systems. I work on both frontend architecture and payment system integration, as well as complex business applications, from real-time to backend.

I have led development teams, driven structuring architectural choices, and actively participated in business decisions, with a pragmatic approach focused on business impact. I pay particular attention to code quality, performance, long-term maintainability, and alignment between technical challenges and product goals.
